Vibration Control of the Composite Wing Model Using Piezoelectric Actuators

摘要

This paper demonstrates the feasibility of using piezoelectric actuators in controlling flow-induced vibration of a lightweight composite wing structure. Vibration characteristics of the composite wing model were predicted analytically against the air flow speed and the results were compared with experimental results from wind tunnel tests. Vibration control tests were successfully accomplished using positive position feedback (PPF) controller and the real-time operating deflection shapes of the composite wing were measured using 3D optical motion capture system.
